Answer:

5/48

Step-by-step explanation:

There are 12 letters in pennsylvania

P (n or a) = (number of n's and a's)/ total

There are 3 n's and 2 a's

P (n or a) = 5/12

P (Vertical symmetry) = letters with vertical symmetry/ total

Only V I and Y have vertical symmetry 3 letters

P ( vertical symmetry) = 3/12

Multiply the probabilities together

5/12 * 3/12 = 15/144 = 5/48

19. Darian loves math and practices every day. He scored the following on his recent practice sessions

zzz [600]

The mean of a set of numbers is the average of the set. To find the mean we must add all the numbers in the set together and divide the sum by how many numbers there are in the set.

95 + 78 + 84 + 86 + 89 + 64 = 496

499 / 6 = 82.67

The mean is 82.67.

The mode of a set of numbers is a number that shows up the most in the set. All the numbers in this set appear once, so, there is no mode.

The median of a set of numbers is the number that is in the very middle of the set. Since the middle has two numbers in it we will find the mean of the two of them.

84 + 86 = 170

170 / 2 = 85

85 is median.

To find the range we need to subtract the smallest number by the largest number.

95 - 64 = 31

31 is the range.

I hope this helps. :)

2x + 3y + x + 7 identidy the terms, like terms, coefficients, and constants in each expression

charle [14.2K]

Answer:

terms, 2x, 3y , x and 7,

like terms, 2x, 3y, x and 7

Coefficient. 2 is the coefficient of 2x and 3 is the coefficient of 2y 1 is the coefficient of x

Constant. 7

Step-by-step explanation:

Given:

$2x+3y+x+7$

Terms are the number of parts in the expression.

there are four terms 2x, 3y , x and 7,

Like terms are the part of the polynomials. 2x, 3y and x are like terms because they both have an x attached. 7 is like terms because they have nothing attached.

The number that are attached to variable is called Coefficient.

So In the term 2x the number 2 is a coefficient because it is attached to x similarly 3y the number 3 is a coefficient because it is attached to y

and in the term x the number 1 is a coefficient.

Constant are the numbers that are not attached to any variable and it is not change. Such as 7 is the constant term.

The sentence is converted into a mathematical equation will be 3n + 5 = n + n + 1/3. Then the correct option is C.

<h3>What is Algebra?</h3>

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Five more than three times the number is one-third more than the sum of the number and itself.

Let the number be n.

Then convert the sentence into a mathematical equation. Then the equation will be

3n + 5 = n + n + 1/3

The sentence is converted into a mathematical equation will be 3n + 5 = n + n + 1/3. Then the correct option is C.

The complete question is attached below.
